# Nextcloud Docker Installation

This repository contains a complete Docker Compose setup for Nextcloud with Traefik reverse proxy and optional NAS storage integration.

## 📋 Prerequisites

- Ubuntu/Debian server with Docker and Docker Compose installed
- Traefik reverse proxy running with Let's Encrypt
- (Optional) NAS storage accessible via SMB/CIFS or NFS
- Domain name pointing to your server

## 🚀 Quick Installation

### Option 1: Automated Installation (Recommended)

Run the installation script which will guide you through the setup:

```bash
chmod +x install.sh
sudo ./install.sh
```

The script will:
- Prompt for domain, admin credentials, and NAS settings
- Install required packages
- Mount NAS storage (if selected)
- Create docker-compose.yml and .env files
- Set proper permissions
- Start Nextcloud

### Option 2: Manual Installation

#### 1. Clone or Download This Repository

```bash
git clone https://forgejo.rozic-dev.com/rozic-dev-server/Nexcloud.git
cd Nexcloud
```

#### 2. Configure Environment Variables

Create a `.env` file:

```bash
cp .env.example .env
nano .env
```

Edit the values:

```env
ADMIN_USERNAME=admin
ADMIN_PASSWORD=your_secure_password_here
NEXTCLOUD_DOMAIN=nextcloud.rozic-dev.com
```

#### 3. Mount NAS Storage (Optional)

If you want to store Nextcloud data on a NAS:

##### Install Required Packages

```bash
sudo apt update
sudo apt install cifs-utils nfs-common
```

##### Create Mount Point

```bash
sudo mkdir -p /mnt/nextcloud
```

##### Mount NAS Share

**For SMB/CIFS (Synology, QNAP, Windows shares):**

```bash
sudo mount -t cifs //NAS_IP/ShareName /mnt/nextcloud \
  -o username=YOUR_USER,password=YOUR_PASS,vers=3.0,uid=33,gid=33,file_mode=0770,dir_mode=0770,noperm,iocharset=utf8
```

**For NFS:**

```bash
sudo mount -t nfs NAS_IP:/volume1/nextcloud /mnt/nextcloud
```

##### Make Mount Persistent (Auto-mount on Boot)

Edit `/etc/fstab`:

```bash
sudo nano /etc/fstab
```

Add this line at the end:

**For SMB/CIFS:**
```
# Nextcloud NAS storage
//192.168.107.90/Data/backup/Nextcloud /mnt/nextcloud cifs username=YOUR_USER,password=YOUR_PASS,vers=3.0,uid=33,gid=33,file_mode=0770,dir_mode=0770,noperm,iocharset=utf8,_netdev,nofail 0 0
```

**For NFS:**
```
# Nextcloud NAS storage  
NAS_IP:/volume1/nextcloud /mnt/nextcloud nfs defaults,_netdev,nofail 0 0
```

##### Test fstab Entry

```bash
sudo umount /mnt/nextcloud
sudo mount -a
df -h | grep nextcloud
```

##### Set Permissions

```bash
sudo chown -R 33:33 /mnt/nextcloud
sudo chmod -R 750 /mnt/nextcloud
```

**Note:** UID/GID 33 is the `www-data` user inside the Nextcloud container.

#### 4. Update docker-compose.yml

If using NAS storage, ensure the volume mount points to your NAS mount:

```yaml
volumes:
  - nextcloud:/var/www/html
  - /mnt/nextcloud:/var/www/html/data  # NAS storage
```

If using local storage:

```yaml
volumes:
  - nextcloud:/var/www/html
  - /mnt/nextcloud/data:/var/www/html/data  # Local storage
```

#### 5. Start Nextcloud

```bash
docker-compose up -d
```

#### 6. Monitor Installation

```bash
docker-compose logs -f nextcloud
```

Wait until you see "Nextcloud was successfully installed"

## 🌐 Access Nextcloud

Open your browser and navigate to:
```
https://nextcloud.rozic-dev.com
```

Login with the credentials from your `.env` file.

## 🔧 Post-Installation Configuration

### 1. Configure Background Jobs (Recommended)

Add a cron job for better performance:

```bash
# Edit root crontab
sudo crontab -e

# Add this line (runs every 5 minutes)
*/5 * * * * docker exec -u www-data nextcloud_server php cron.php
```

Then in Nextcloud:
1. Go to **Settings** → **Administration** → **Basic settings**
2. Change background jobs from "AJAX" to "Cron"

### 2. Configure Email (Optional)

In Nextcloud admin settings, configure SMTP for password resets and notifications.

### 3. Install Recommended Apps

Go to **Apps** and install:
- Calendar
- Contacts
- Tasks
- Talk (for video calls)
- Deck (Kanban board)

### 4. Configure External Storage (Alternative to NAS mount)

If you prefer to use Nextcloud's external storage feature instead of direct NAS mounting:

1. Enable the "External storage support" app
2. Go to **Settings** → **Administration** → **External storage**
3. Add your NAS as SMB/CIFS or NFS storage

## 📊 Management Commands

## 🔒 Security Notes

1. **Change default passwords** in production (database, Redis, admin)
2. **Enable 2FA** for admin account
3. **Regular backups** of database and data directory
4. **Keep Docker images updated** regularly
5. **Use strong passwords** for NAS and Nextcloud admin
6. **Restrict file permissions** on .env file:
   ```bash
   chmod 600 .env
   ```

## 🐛 Troubleshooting

### NAS Mount Issues

**Check if mounted:**
```bash
df -h | grep nextcloud
mount | grep nextcloud
```

**Test NAS connection:**
```bash
ping NAS_IP
smbclient -L //NAS_IP -U username
```

**Remount manually:**
```bash
sudo umount /mnt/nextcloud
sudo mount -a
```

**Check mount logs:**
```bash
dmesg | grep -i cifs
journalctl -xe | grep mount
```

### Permission Issues

If you get permission errors:

```bash
# Fix data directory permissions
sudo chown -R 33:33 /mnt/nextcloud
sudo chmod -R 750 /mnt/nextcloud

# Restart Nextcloud
docker-compose restart nextcloud
```

### Database Connection Issues

```bash
# Check if MariaDB is running
docker-compose ps mariadb

# View MariaDB logs
docker-compose logs mariadb

# Test database connection
docker exec -it nextcloud_mariadb mysql -u nextcloud -pnextcloud nextcloud
```

### Redis Connection Issues

```bash
# Check Redis
docker-compose ps redis

# Test Redis connection
docker exec -it nextcloud_redis redis-cli -a nextcloud ping
```

### Nextcloud Shows "Access through untrusted domain"

Add your domain to trusted domains:

```bash
docker exec -u www-data nextcloud_server php occ config:system:set trusted_domains 1 --value=your-domain.com
```

### Clear Installation and Start Fresh

```bash
# Stop containers
docker-compose down

# Remove volumes (WARNING: This deletes all data!)
docker volume rm nextcloud_mysql nextcloud_redis nextcloud_nextcloud

# Clear data directory
sudo rm -rf /mnt/nextcloud/data/*

# Start again
docker-compose up -d
```

Or use the cleanup script:
```bash
chmod +x remove-data.sh
sudo ./remove-data.sh
```

## 📝 Notes

- **Data Location**: All user files are stored in `/mnt/nextcloud` (or your configured NAS path)
- **Database**: MariaDB 10.11 with optimized settings for Nextcloud
- **Redis**: Used for session handling and caching
- **Traefik**: Handles SSL certificates via Let's Encrypt automatically
- **Backups**: Remember to backup both database and data directory regularly

## 💡 Tips

1. **Performance**: Use Redis for memory caching to improve performance
2. **Storage**: Monitor disk space regularly, especially if storing large files
3. **Updates**: Always backup before updating Nextcloud
4. **Apps**: Only install apps you actually need to keep system lean
5. **Monitoring**: Set up monitoring for disk space and service health
